Electromagnetic vibratory screen - with fines compartment completely enclosed to prevent dust pollution

摘要

Powders and granular materials are sieved on an electromagnetic, vibratory, screening machine which has the screen completely enclosed in a case, with a fines collecting compartment between the screen and the base of the case which is connected by push-rods to the screen and which has the vibrator unit secured to its outer face; the base is resiliently deflectable so that the unit, the base, the pushrods and the screen all oscillate in unison. The fines compartment is open only at its discharge end, so noxious materials may be handled safely; the vibrator is outside the case for cleanliness and easy access.
